I think this is a problem with Spotify and not my computer, but suddenly I'm having problems with the volume. I'm using the web version (Chrome) on an iMac desktop. I'll be listening with earphones, with the volume set on Spotify at about 70% and all of a sudden, in the middle of a song without me having touched anything, it will jump up to 100%. I fix it and it happens again after a few minutes. Is anyone else having this problem? This just started today.
